Product Description The Light Rain Radar (SRR-100) acquires the Doppler power spectrum and uses the empirical formula for the falling velocity and diameter of precipitation particles to invert the raindrop spectrum at different heights. It can obtain the vertical profile distributions of parameters such as the Doppler power spectrum, reflectivity factor, Doppler velocity, path-integrated attenuation, raindrop spectrum, rainfall rate, and liquid water content within the vertical range of 0-6 kilometers. All calculations are integrated into the outdoor electronic equipment, which has a built-in embedded Windows operating system and powerful data analysis and storage functions, making it suitable for field observations.
